Settling behavior of fine cuttings in fiber-containing polyanionic fluids for drilling and hole cleaning application
(
Elsevier B.V.
, 2021 , Article)
For efficient drilling operations, cuttings transport within the oil and gas wellbore is fundamental. Inadequate hole cleaning results in many problems including reduced rate of penetration, increased torque, bit wearing, ...
Computational Screening of Potential Inhibitors of Desulfobacter postgatei for Pyrite Scale Prevention in Oil and Gas Wells
(
American Chemical Society
, 2021 , Article)
Sulfate-reducing bacteria (SRB), such as Desulfobacter postgatei are found in oil wells. However, they lead to the release of hydrogen sulfide. This in turn leads to the iron sulfide scale formation (pyrite). ATP sulfurylase ...
The effect of vacancy defects on the adsorption of methane on calcite 104 surface
(
Elsevier Editora Ltda
, 2021 , Article)
Density functional theory calculations are used to study the effect of vacancy defects (ionic Ca and charge neutral CO3) on the adsorption properties of CH4 molecule on different calcite surfaces. Both types of vacancy ...
Assessing the relation between mud components and rheology for loss circulation prevention using polymeric gels: A machine learning approach
(
MDPI AG
, 2021 , Article)
The traditional way to mitigate loss circulation in drilling operations is to use preventative and curative materials. However, it is difficult to quantify the amount of materials from every possible combination to produce ...
Development of oil formation volume factor model using adaptive neuro-fuzzy inference systems ANFIS
(
Society of Petroleum Engineers
, 2021 , Conference Paper)
The oil formation volume factor is one of the main reservoir fluid properties that plays a crucial role in designing successful field development planning and oil and gas production optimization. The oil formation volume ...
A robust fuzzy logic-based model for predicting the critical total drawdown in sand production in oil and gas wells
(
Public Library of Science
, 2021 , Article)
Sand management is essential for enhancing the production in oil and gas reservoirs. The critical total drawdown (CTD) is used as a reliable indicator of the onset of sand production; hence, its accurate prediction is very ...
Investigation on the effect of mud additives on the gelation performance of PAM/PEI system for lost circulation control
(
Society of Petroleum Engineers
, 2021 , Conference Paper)
Lost circulation is one of the most common problems in the drilling of oil and gas wells where mud escapes through natural or induced fractures. Lost circulation can have severe consequences from increasing the operational ...
Impact of clays on CO2 adsorption and enhanced gas recovery in sandstone reservoirs
(
Elsevier Ltd
, 2021 , Article)
Carbon dioxide enhanced gas recovery (EGR) is a promising technique to sequester CO2 and boost natural gas recovery from conventional depleted and unconventional tight gas reservoirs. Clay minerals are usually present in ...
Electrochemical removal of pyrite scale using green formulations
(
Nature Research
, 2021 , Article)
Pyrite scale formation is a critical problem in the hydrocarbon production industry; it affects the flow of hydrocarbon within the reservoir and the surface facilities. Treatments with inorganic acids, such as HCl, results ...
Gelation kinetics of functionalized silica crosslinked polymeric gels used in conformance control applications
(
John Wiley and Sons Inc
, 2021 , Article)
The potential crosslinking of three types of nitrogen-containing functionalized silica (TAAcONa, guanidine, and triamine) with polyacrylamide (PAM) has been investigated. Only triamine silica was able to crosslink with ...
